Hi,
The XML Processing Model Requirements Note [1] states as a design
principle that XML documents are operated on as infosets, which
presumably refers to the XML Infoset [2].
However, at the end of the last telcon, Henry brought up the
requirement to access the [validity] and [validation attempted]
properties of the PSVI [3]. As well as the PSVI, I think that it's
essential to be able to pass XQuery 1.0/XPath 2.0 data models [4],
which are also augmented infosets, between processes.
At the other end of the spectrum, there are XML processes that need to
accept or produce serialized XML, such as canonicalization [5] or
simple regex-based processing.
I think that one of the requirements for the XML Processing
Model/Language is that it needs to support passing XML documents in
the forms of serialised XML, infosets *and* augmented infosets, as
appropriate, between processes in a pipeline. Other thoughts?
Cheers,
Jeni
